A table tripod that is a tube with legs that fold and slide into.
Last time I flew (6:00 AM out of ABQ Nov. 2007) it was 3 spice jars of NM ground chile (I had a bag of dried NM reds as well). Meanwhile, during the bag search, I put my hand in my pants pocket, and realized I had walked right through the WTMD with keys and change in my pocket.

My GF was getting her usual pat-down, for flying while Chinese or flying while wearing an underwire bra, or something....
